4. 2009/6/24 4 ISO 1087-1 and MDR CONCEPT Referent Refers To Symbolizes Stands For “Rose”, “ClipArt”  Real world 3.2 Concept 3.4 Designations 3.5 Terminology 3.3 Definition Example: concept, concept system Example: designation, nomenclature, definition  Representation world  Concept world MDR Example: Concept, Concept_System Very confusing

5. 2009/6/24 5 Meaning triangle and RDF, OWL, Common Logic etc. A model, which is an interpretation that makes all the sentences true, may be interpreted as a concept system since it is a kind of function from Representation world. Most of ontology languages such as RDF, OWL, Common Logic etc. handles Real world and Representation world only.

7. 2009/6/24 7 Inconsistency of term definition in MDR CONCEPT Referent Refers To Symbolizes Stands For “Rose”, “ClipArt”  Real world 3.2 Concept Concept and relation lie in the different world. (cf. JPN-p01-005) Example: concept, concept systemC  Representation world  Concept world MDR uses the definitions of ISO 1087-1 for concept and concept system. Relation is defined in terms of universe of discourse in MDR. Universe of discourse lies in Real world both in the sense of TR9007 and ISO/IEC 24707 Common Logic. relation, universe of discourse
